Deleting samples at the beginning or end of chop
Sometimes you want to delete certain parts of a chop. For example when you have an audiospectrum that doesn't really provide usefull data at the edges we can use a trimCHOP to delete certain numbers of samples at the outer edges. For that we set unit values to Relative Start/End and discard Exterior. From there you can set the amount of samples you want delete in Start and End.
